As a universal concept in nonlinear science, synchronization has been broadly interested and extensively studied over the past decades. Whereas numerical and theoretical studies have unveiled abundant synchronization phenomena in coupled oscillators, few of them have been replicated in experiments, due to the sensitivity the synchronization dynamics to the noise perturbations and parameter mismatches. In the work by Jing Zhang, et al., the authors designed a new experimental setup to explore the synchronization patterns in asymmetrically coupled metronomes. By varying the initial conditions and coupling parameter, different synchronous patterns are generated and identified based on the audio signals. In particular, a new type of synchronous pattern, namely the in-phase delay synchronization state (IPDS), is reported for the first time, which is rooted in the breaking of the system symmetry. By a theoretical model, the authors also conducted a detailed analysis on the basin and transition properties of the patterns, which, together with the experimental findings, give a complete picture on the synchronization behaviors in coupled metronomes.
